代码如下：

[csharp] view plaincopy
 using UnityEngine;
using System.Collections;
using System.IO;  

public class DownPicture : MonoBehaviour {  

    public GameObject plane;
    WWW www;
    string filePath;
    Texture2D test;
    Texture2D newTexture;
    // Use this for initialization
    void Start () {  

        filePath = Application.dataPath + "/Resources/picture.jpg";  

        if (System.IO.File.Exists(filePath))
        {
            Debug.Log("文件已存在");
            test = (Texture2D)Resources.Load("picture", typeof(Texture2D));
            plane.renderer.material.mainTexture = test;
        }
        else
        {
            Debug.Log("文件开始下载");
            StartCoroutine(GetImage());  

        }  

    }  

    // Update is called once per frame
    void Update ()
    {  

    }  

    IEnumerator GetImage()
    {
        string url = "http://192.168.2.105:8080/Test/picture/1.jpg";  

        www = new WWW(url);
        yield return www;
        newTexture = www.texture;  

        byte[] pngData = newTexture.EncodeToPNG();
        File.WriteAllBytes(filePath, pngData);  

    }  

    void OnGUI()
    {  

        if (www.isDone)
            {
                plane.renderer.material.mainTexture = newTexture;  

            }
    }
}
